OpenRefine 3.8.1 – Clean, transform, extend messy data.
OpenRefine is a powerful free, open source tool for working with messy data: cleaning it; transforming it from one format into another; and extending it with web services and external data.
Main features:
Faceting – Drill through large datasets using facets and apply operations on filtered views of your dataset.
Clustering – Fix inconsistencies by merging similar values thanks to powerful heuristics.
Reconciliation – Match your dataset to external databases via reconciliation services.
Infinite undo/redo – Rewind to any previous state of your dataset and replay your operation history on a new version of it.
Privacy – Your data is cleaned on your machine, not in some dubious data laundering cloud.
Wikibase – Contribute to Wikidata, the free knowledge base anyone can edit, and other Wikibase instances.
